Sorry to take so long to respond - I missed this post!
I'm sorry also that I don't know which Jovibarba I have, they were a bulk deal with no labels, as they are really hard to find I just grabbed at the chance!
For the zone, I am in Canadian zone 5a, and I think that is pretty much the same as the USDA one.
From your pics, I have Violet, Purple Haze and Sundancer, as well as several of what I call sobolifera or allionii, as they are rounded with the pointed leaves - these never really open up, not like the heufellii. I'll try and id them and let you know.
As for hardiness, I only lost the one type, and again, it was noid. I will try and keep track better in the future. I'm going to run into the same problem as I bought several types of seeds for Jovibarba and Sempervivum, of which four have come up - and there are billions! Well, not quite, but you know what I mean - whatever will I do with them all....
